I don't think I've seen this posted.. Christchurch, New Zealand, shattered by a 2011 earthquake, offers an urgent lesson for California. Eight years ago, a huge earthquake ruptured directly under Christchurch, killing 185 people. Full recovery remains elusive.
The city offers an urgent lesson to California, whose major cities — situated along seismic faults — face similar threats.
New Zealand and California have similar seismic safety standards, their skylines built in the 19th century with collapse-prone brick and in the 20th century with brittle concrete. Each also sits on the edge of a huge tectonic plate boundary. Neighborhoods are built on top of soft sediment that magnifies the shaking, and seismic regulations for older buildings in many areas are inadequate to resist collapse from intense shaking.
Recovery from a huge quake in Southern California or the San Francisco Bay Area would be many times more challenging than in Christchurch, given the state’s huge population, housing shortage and sprawling infrastructure.
